Dear All, I do have a problem while reading in more than 20 cel files using ReadAffy(= ). The error message is : can=B4t allocate vector. Can anybody help? Thank=B4s in advance Joerg [[alternate HTML version deleted]]

First off, it is difficult to help if you don't give any more information such as your OS, R version, affy version, etc. Because there was an HTML version to this email, I will assume you are on windoze. You can allocate more memory for R by appending --max-mem- size=<however much="" ram="" you="" have=""> to the command line for starting R, or by using memory.limit(size=<ram in="" bytes="">) from within R. However, R is supposed to be much better about grabbing whatever RAM it needs in versions > 1.5 or so, so this may not really help. If this doesn't work, try justRMA in the development version of affy. All it does is RMA, but it takes much less memory. Jim James W. MacDonald UMCCC Microarray Core Facility 1500 E.
